If you have a model which is only 1 color, you can assign the second print core to printing support materials in Cura. (Use BB for PVA).

Sounds like the installation instructions could be a bit clearer if @Ronan did not benefit optimally from a new version. I'll see if some instructions can be included with the next release.

De volgende Ultimaker Session komt er weer aan. Dus het wordt tijd om te delen wat het onderwerp is van deze editie.. Een Exoskelet! De TU Delft wordt wel vaker in verband gebracht met innovatieve en indrukwekkende projecten, en dat is dit maal niet anders. 'Project March' is een nieuw project, waar een team achter schuil gaat dat een sportief exoskelet aan het ontwerpen en bouwen is. Het doel wat ze zich hebben voorgenomen is om het parcours van Cybathlon 2017 onder 10 minuten af te ronden. Wedstrijden zoals deze zijn natuurlijk spannend en leuk, maar het is niet ongebruikelijk dat innovaties uit competities later geadopteerd worden in de 'normale' wereld. Heel leuk en aardig, maar waarom komen ze naar een Ultimaker Session? Nou wil het net zo zijn, dat Project March ook Ultimaker 3D printers gebruiken om prototypes te maken voor hun exoskelet. Behalve dat ze dit in staat stellen om snel prototypes te maken, onderdelen kunnen passen en testen, moet een exoskelet haarfijn afgesteld en ontworpen zijn om de 'gebruiker'. De combinatie tussen 3D scannen en 3D printen is hier goud. Project March komt vertellen waar ze 3D printen voor gebruiken, wat de uitdagingen waren en hoe dat dit te implementeren is in een exoskelet. Ben jij geinteresseerd om meer te weten over exoskeletten, 3D printen en / of prototypen met een Ultimaker, kom dan zeker even langs! Project March neemt een aantal van hun prototypes mee om te presenteren. Helaas was het niet mogelijk het hele exoskelet mee te nemen. Let er op, Protospace is van locatie veranderd! De nieuwe locatie heeft zelf geen parkeerplaats, maar er liggen er wel 2 vlak om de hoek. Namelijk de parkeergarage aan de Cambridgelaan en de parkeerplaats aan de Padualaan. Wij hebben de vorige keer aan de Padualaan geparkeerd, welke maar een paar minuten lopen was van Protospace. We zijn wel eerst de ingang 2 keer voorbij gereden, daarom hebben we deze aangegeven op de kaart hieronder, bij de grote blauwe stip aan de Leuvenlaan. Datum: 27-03-2017. Locatie: Protospace, Padualaan 99 Planning: 17.00 - 18.00 Deuren open. Je kan ook gezellig mee eten (10 euro pp, cash or card) 18.30 - 19.00 Presentatie 19.00 - 21.00 Naborrelen 22:00 Einde We zouden het op prijs stellen als je kon RSVP'en via deze link. Bedankt!!

What default profile do you use and what are your slight mods for PVA? From which supplier do you get your filament?

Makes sense! Small investment to rule out any risks.

Hi @lschachtner, thank you for your post and welcome to our community! Congratulations on your new Ultimaker 3. How has it been working for you so far? About your bed leveling, it may be difficult to see how well your first thin (transparant) layer sits on your (transparant) glass bed. It is a known 'thing' that it is difficult to see with transparant filament. Do you also have other colors available to run a test with? I am not sure if some patterns you see here are just amplified due to the transparant filament or if it indeed something to do with the leveling. If you could do a print with like red or blue or silver that would probably be a bit easier to diagnose. Besides this; how did the print finish? OK?

Hi @exforma23, I also like manual leveling. When done well and you don't move your Ultimaker around too much, or have to take out your glass plate every other print it should be good for months. It also only takes a few moments. However, with the connectivity and starting printjobs from a distance, sometimes you can not know or take the risk in hoping it is leveled correctly. In those cased, the active leveling can be of great help. Happy to hear your springs did the job, and you can continue to 3D print!

@Grasmier, thank you for your reply. Good to hear that the network features should work fine for you. I think your question about the NFC was also answered? Were there any other questions you had regarding the Ultimaker 3? Prototyping of small medical devices sounds very interesting. Prototyping is very widely used application of 3D printing, in a large variety of fields. And we can totally see why. How small are the devices you will be making? Do they come with certain design challenges, or perhaps challenges to get them 3D printed? Have a good day,

Hi @Ronan, thank you for your message. We are continuously working on improving the prime tower. Our apologies if it has been giving you trouble. While our software team is busy implementing improvements (there are some theories), perhaps this post of @GR5 could help you in the mean time. He adds some support to the prime tower that should prevent it from tipping over. The problem lies in the adhesion / bonding between PVA and PLA. @Exforma23, thank you for your message and welcome to the forums! Why exactly are you looking for a replacement for your glue? Has it not been working for you? Fair chance you may want to improve your bed level instead of looking for a different adhesive. If you have bed-adhesion issues, they are probably different from why Ronan created this post. (Wipe-tower breaking has nothing to do with bed adhesion). I know glue works great, but it is not the only thing that works great. There are alternatives. Unfortunately I have never tried 3D Lac. If you are gonna use a spray, make sure you remove your glass plate from your Ultimaker so you don't cover the entire insides of the machine with sticky spray

That is pretty cool! I don't know what the rest of the bottom of that print looks like, but if it is 'just' that hole, would you really need supports for that? By the size of it it looks like you could make it by bridging alone?

The next Ultimaker Session is around the corner. Time to reveal what we will gather around for this time... If you are interested in 3D printing you must have heard of e-nable by now. It's like that kid in the classroom that everyone likes. And that kid is about to get a new best friend. We can leave it up to the ‘Technische Universiteit Delft’ (TU Delft) to amaze us with this fantastic project. ‘Project March’ is the name it goes by, and the team behind it is developing a sporty exoskeleton to take part in competitions and contribute to the development of this technology. One of their goals is to finish the Cybathlon 2017 track under 10 minutes, which is a real challenge. Project March also uses Ultimaker 3D printers to prototype parts of their exoskeleton. They have agreed to visit this Ultimaker Session and will bring a couple of prototype parts of their exoskeleton that they have 3D printed and tell us more about their developments. If you want to know more about how an exoskeleton works, where that technology is headed or want to learn more about prototyping with a 3D printer in general? Make sure to stop by! Unfortunately I just heard 'Project March' won't be able to bring the entire exoskeleton. They have promised to bring some very interesting examples of what they made with them, so I am excited to see what it will be! We are looking forward seeing you on Protospace's new location! This location has no carpark of its own, but there are two (paid) parking spaces nearby you can use: parking garage Cambridgelaan and parking lot Padualaan. We parked at the Padualaan last time, which was only a 4 minutes walk from Protospace. The entrance to the parking lot is easily missed though. I have marked it with the blue dot at the Leuvenlaan. Date: 27-03-2017. Location: Protospace, Padualaan 99 Schedule: 17.00 - 18.00 Doors open. You can also order food (10 euro pp, cash or card) 18.30 - 19.00 Presentation 19.00 - 21.00 Drinks and discussions 22:00 Wrap up We would appreciate it if you could RSVP following this link. Thank you!!

Hi @Grasmier, thank you for your message and welcome to the community! What type of company will the Ultimaker 3 hopefully find a place in? Will you be prototyping, make end-use products or something else? I'm always curious to learn about the uses of 3D printing. About your questions, it is possible to connect your Ultimaker 3 to internet using an ethernet cable. How it exactly fits in in your network topology I am not exactly sure. Also not an expert here Perhaps @Nallath knows the answer? I do know that if you want to send a project to print, the station from which you send it must be connected to the same network as the Ultimaker 3. You can also not just take control of the Ultimaker 3, this needs to be authorized on the physical Ultimaker 3 first. You can bypass this network by setting up a VPN, do you know if that is allowed? About your second question, I can be of more help. The NFC chip is installed to make it easier and more reliable to use Ultimaker filaments. But it is in no way a limiting factor. We have a materials team who made default profiles for every material we have, and every color in which material is available. Due to the pigments that define the color, the profile of Ultimaker PLA White may vary slightly from Ultimaker PLA Orange. These settings will immediately be loaded if the material is being detected by the NFC chip. In the scenario of using NinjaFlex, you just select (for example) PLA, and you get a standard profile. This may require some more tweaking to get this profile right, but this would be the 'normal' scenario when we would not have a NFC reader at all. So it just makes it easier when you use Ultimaker filaments, nothing more and nothing less I would like to advice to not start with NinjaFlex in general. Ultimaker has a bowden tube system and this makes printing flexible materials slightly more tricky. One or two drops of sewing machine oil in the bowden tube, printing at 20mm/s at 240ºC should get you started. But I would recommend starting with regular PLA or Nylon to get a feel for your new Ultimaker and 3D printing. Once you are more familiar with it you can start with more expert materials like NinjaFlex. (We also have TPU, which is also flexible material). If you have any further questions, looking forward hearing from you!

Hi @Tiger91, thank you for your feedback. Going back to basics, could you set your feeder to the recommended tension (middle), use your Ultimaker red PLA and use a default profile from Cura 2.4? Could you include a photo of the model you are trying to print? Is it old or relatively new PLA? Have you tried different materials, to rule out you might be dealing with a bad reel of filament (if so, would be unfair to blame the printer). Are you using your AA print core for PLA Red? AA for PLA / Nylon / ABS etc and BB is for PVA. The print core is not suppose to jam and should be pretty reliable. I am pretty sure we can help diagnose what is not working as it should in your case, but we need some more information to do so. Looking forward to hear from you.

Not a lot I can add to this I think, except one thought I had about the proposed printing times in S3D. It may give you some estimation of how fast a printhead can move around, but you can only know how realistic this is if you have also seen and compared the print quality this generated. Or even if you pushed beyond these estimations to see if it indeed is the limit. I don't own a prusa so I can't really draw the comparison but obviously I agree with the reliability of Ultimaker. And even more with the kuddo's to this amazing community Hopefully you feel welcome here, even when you don't have your Ultimaker 2 Extended+ yet and continue fiddling with your Prusa.

Hi @Wisar, Thank you for your post, sorry to hear about the difficulties you have with your Ultimaker 3. Has your Ultimaker already made its way to 3DGBIRE, or what is the current status? I think a lot of the remedies mentioned here make sense when the clog is in the nozzle, but recently there was mention of a clog in a print core in a different place. Check out this photo. Your description of your clog could mean something like this happened to you too. In that case, it is assumed it could happen because the third fan in the print head did not work. Otherwise it should be impossible. Do you know if yours work(s/ed)? I am pretty sure 3DGBIRE will do their best to help you like they have done in the past and make sure you can get back to 3D printing. I do feel slightly obligated to mention that the Ultimaker 3 has been perfectly dialed in for our filaments and Cura, and using third party filaments (or s3D) may require some extra attention or caution as they may behave differently. Not saying you are to blame, but there may be a difference in bed adhesion, layer bonding, strength / brittle etc. So your 3D print experience may be different, maybe even a bit more risky, than what you grew familiar to.

Hi @Bschulte, thank you for your post and welcome to our community! The freedom in which you can align or position your models on your buildplate may depend on some of the settings you have enabled in Cura. It may depend on if you have selected print all at once or print at the same time (option under 'special modes'). It may also depend on if you have a brim selected or not, and if you print something in dual or single. For example, when you print in dual, you can enable or disable a wipe tower. The wipe tower is a helper part, and will be positioned in the back right corner. For that reason, you can not put your model there. Hopefully this helps. Otherwise, I would appreciate it if you could add an image of what your buildplate looks like, that way we can offer some more help.

Hi @Fabreax, thank you for your message. I've seen your message before the weekend but I wanted to make sure that my reply would be correct so I was waiting for some feedback from my colleagues. First of all, sorry to hear you are having some issues with your LED's. But it looks like it shouldn't be a difficult problem to fix. Perhaps something you could do yourself, but I can imagine, if you have some warranty coverage, you would prefer that route. I checked with my colleague from support, and they said that we continue to help and support our customers within the warranty period, even if the Ultimaker is second hand. Perhaps there was a mistake with Makershop, or some confusion but you should be happy to know you get the help you deserve to solve this. I would like to ask you to get in touch with Ultimaker and we will connect you with Makershop and get things sorted. I will DM you with some specific instructions. Hopefully this helps, if you have any further questions please feel free to ask

Hi Jogral, Thank you for your message and welcome to the forums! Before you buy a 3D Printer, I would like to invite you to look up some user experiences from different vendors and include that in your decision making process. The files you can find on thingiverse can be used for practically all 3D printers, so also Makerbot and Ultimaker. But just in case, Ultimaker is also connected to a repository called youmagine.com What do you need a 3D printer to do, in order to make your best heels? What materials do you want to use? How big are those heels? What quality do you expect? Do you ever want to make anything else except heels? Are you looking to make a final product or prototypes?

Let me check

Seems like different nozzles made a big difference! Curious to see how it will continue. Did you also use PetG as that thread you refer to, or is this PLA? If PetG, why did you choose that over PLA?

@Tomnagel, in his first post Brannfjell describes he raised the temperature to 300ºC. Should the heatbreak and front fan prevent affects from temperatures this high too?

Hi Less, good to hear you are back! Hopefully it was nothing serious while you were gone. Your project looks really good! Curious to see what Ivan will grow into!

Hi @Brannfjell, thank you for your post. First of all, I would strongly recommend against using a heatgun. You will probably break something before you fix something. Is there still any filament in your feeder, or is it all out? Is it only still stuck in your printhead / Core AA? Are you sure it is PLA? I would recommend to only pull. If you decide to push, make sure your printhead is parked in the corner of your build Ultimaker, to prevent your force to bend the rods. If it is indeed, PLA, raising the temperature to 200ºC should be enough to pull it out from the print core. Especially if you give it a minute or two before you give it a pull.

Hi @mprowe, Welcome to the Ultimaker community! There could be a couple of things, have you checked if the emails did not end up somewhere in your spam filter? They are sent from noreply@. Next, did you enable the email notification setting? You can find it by following this route: Click on your username top right > Settings > Notifications > there you can select which events you want to receive an email from. Let me know if this helps, or if you have any further questions! Have a great day!
